productivity - Opis:
- The paper provides a description and analysis of the provenance experiment established in Zielonka Experimental Forest District. The greatest productivity was found for Scots pine from the Milicz Forest District known in literature as Kubryk provenance followed by the local population from Stęszewko. The poorest productivity revealed pine from Nowy Targ. The observed differences amounting to 120 m3·ha–1 are statistically and economically significant. Negative correlation of taxation parameters with east longitude has been ascertained. The regularity that local provenances occupy high−ranking position in provenance test results has also been proven. A high rank of the local provenance when compared to known provenances showing high plasticity and productivity (Miłomłyn, Prószków and Milicz) allows to state that the pine selection programme for Zielonka and other neighbour Forest Districts should be based on local resources.
